In the DELETE executor, tuples were being locked\deleted using the command ID returned by GetCurrentCommandId(). However, the original tuples were retrieved using a command ID stored in the estate. To fix it- before the retrieval of a tuple, estate command IDs are set using GetCurrentCommandId() so it matches if the tuple is to be deleted later. Additional changes: ------------------- Fixed an incorrect cypher_delete test. The query `MATCH (n1)-[e]->() DELETE n1, e RETURN n1` should be able to delete n1 and e without requiring DETACH DELETE. TODO: ----- It may be a good idea to audit the executors for any inconsistent use of command IDs.
